2. Automotive air conditioning - Wikipedia

   en.wikipedia.org/wiki/Automotive_air_conditioning

   R-12, the first automotive air conditioning refrigerant, was invented in 1928 by a team of scientists put together by Thomas Midgley, Jr. The team of scientists set out to create refrigerants which led to the invention of chlorofluorocarbons (CFCs) and hydrochlorofluorocarbons (HCFCs). From these two inventions, two refrigerants were created, R ...

3. Thermostat - Wikipedia

   en.wikipedia.org/wiki/Thermostat

   A pneumatic thermostat is a thermostat that controls a heating or cooling system via a series of air-filled control tubes. This "control air" system responds to the pressure changes (due to temperature) in the control tube to activate heating or cooling when required. The control air typically is maintained on "mains" at 15-18 psi (although ...

4. Thermal expansion valve - Wikipedia

   en.wikipedia.org/wiki/Thermal_expansion_valve

   A thermal expansion valve or thermostatic expansion valve (often abbreviated as TEV, TXV, or TX valve) is a component in vapor-compression refrigeration and air conditioning systems that controls the amount of refrigerant released into the evaporator and is intended to regulate the superheat of the refrigerant that flows out of the evaporator ...

5. Weather Eye - Wikipedia

   en.wikipedia.org/wiki/Weather_Eye

   The optional air conditioning system offered by Oldsmobile cost $199 more, and it weighed twice as much as the integrated Nash unit that added only 133 pounds (60 kg). [19] A feature was the "desert only" setting on the A/C thermostat control, a position that typically ran the compressor continually.

6. Radiator (engine cooling) - Wikipedia

   en.wikipedia.org/wiki/Radiator_(engine_cooling)

   a thermostat to control temperature by varying the amount of coolant going to the radiator; a fan to draw cool air through the radiator. The combustion process produces a large amount of heat. If heat were allowed to increase unchecked, detonation would occur, and components outside the engine would fail due to excessive temperature. To combat ...

7. Heater core - Wikipedia

   en.wikipedia.org/wiki/Heater_core

   A heater core is a radiator -like device used in heating the cabin of a vehicle. Hot coolant from the vehicle's engine is passed through a winding tube of the core, a heat exchanger between coolant and cabin air. Fins attached to the core tubes serve to increase surface area for heat transfer to air that is forced past them by a fan, thereby ...
